Use the EL functions from `tc:format1` to `tc:format9` to replace up to 9 variables in a given internationalized text. This work like in .

The message format is: "#{format1text}"

<tc:out value="\#{tc:format1(format1text, 695700)}"/>

The message format is: "#{format3text}"

<tc:out value="\#{tc:format3(format3text, 5800, 15700000, 5000000)}"/>

The message format is: "#{format9text}"

<tc:out value="\#{tc:format9(format9text, 0, 1, 2, 3, 4, 5, 6, 7, 8)}"/>

You may also use the `fn:` function library for string manipulation.

<tc:out value="\#{fn:toUpperCase('uppercase')}"/>
